How can a dealership, arbitrarily define that all Puerto Rico falls under the 'extreme driving conditions' category?

I went with my sister to the dealership in Puerto Rico to have her car (2013 Sonata) go through the 7,000 miles maintenance. I was surprised when the person mentioned that the car needed oil change (it had been changed at 3,000 -without me knowing it). I questioned that! She showed me the car booklet which showed in the section of 'Severe Driving Conditions' PR (to my surprise 'handwritten' by the Hyundai technician. I believe this is questionable and unsustainable. I am looking to have that statement in a formal document from Hyundai PR. Do you have any comments?

The old rule was 3 months or 3000, some of the newer cars are
extending that out. From what I've heard about roads in Puerto Rico it
would have a classification of severe duty so I would stay with the 3000
oil change just to help your engine last as long as possible.

Severe driving conditions can mean short trips (under 10 miles), dusty
conditions and extreme weather. If your oil change costs you $60,
then that adds 2 cents per mile to your driving cost. Even if you were
to get 35 miles per gallon, your gasoline costs per mile are 12.2 cents
per mile when gasoline costs $4.29 per gallon. Keeping your engine
clean will make it last longer and should give you better gas mileage
also. If you save 1 cents a mile on your oil, that is only $1,000 for
every 100,000 miles. engine replacement is very costly.
